General Notes and Tips on
Signal Conditioning
In addition to this section (= general notes) you will find specific notes
and tips on signal conditioning according to the I/O units of the board.
You should also refer to these.
Noise, crosstalk and inductive effects can degrade the signal and lead
to incorrect results if the following are not performed correctly:

ADC performance of
dSPACE boards
When you are sampling an unconnected A/D input, you are looking at
a noisy signal traced in ControlDesk. This may give the impression that
the performance of the A/D sections of dSPACE boards is poor.
For an explanation of this incorrect impression and further background
information (definition of SNR, measuring noise), refer to
ADC
Performance of dSPACE Boards
on page 153.
